General

Only people who are lucky get good/rare stuff, like so far I got 24 chairs from the Kaleido wheel from the first day

I just want the level 75 set, I rather buy it in the fm than get it myself and waste tons of nx for a chance to get nothing good.

Rewards include:

Equipment upgrade items: Chaos (a variety), Weapon ATT/Magic ATT, Enchancement Scrolls (2 Star, 3 Star), Potential Scrolls (Special, Epic), Slot Carvers (Silver, Gold), Awakening Stamps (Silver, Gold)
Chairs: Grey Seal Cushion, Gold Seal Cushion, Kadomatsu, Skull Throne, Ice Chair, Giant Pink Bean Cushion, Cuddly Polar Bear, Ryko Chair, Amorian Loveseat
Equips: Fearless weapons, Abyss weapons, Loveless weapons, Sovreign armor
and more
